Abstract

Background:

Reduced forced expiratory volume in 1 second percentage (FEV1%) predicted is closely related to cardiovascular mortality. However, evidence regarding the correlation between FEV1% predicted and the severity of coronary atherosclerosis observed on coronary angiography is still limited. We aimed to explore whether a decline in FEV1% predicted was associated with diffuse coronary atherosclerosis in hospitalized patients.

Methods:

A cross-sectional study enrolling hospitalized patients with cardiovascular symptoms undergoing both coronary angiography and lung function testing was conducted. The correlation between FEV1% predicted and angiographic characteristics, including the number of diseased vessels, total number of coronary lesions and Gensini score was analyzed.
